加强中小型断层的预测促进煤矿安全生产

Improvement of the prediction of small-medium scale faults for the security of coal mining

煤矿生产主要是井下作业 ,由于其作业环境的特殊性 ,安全生产至关重要 ,而影响煤矿安全生产的突出隐患为水、火、瓦斯、煤尘、顶板。其中水、瓦斯、顶板又与地质构造的变化有着直接的关系。断层是影响煤矿安全生产的重要地质因素 ,关系到矿井的经济效益和社会效益。对于断层的分析预测直接关系到煤矿的安全生产 ,采掘接替及煤炭资源的合理开发和利用。文章根据朔里煤矿在实际生产过程中所揭露的断层情况 ,结合多年来的工作经验探讨中小型断层定向预测的几种方法 ,如 :煤岩层位对比法、构造对比法、利用断层带的特征、利用断层两侧的派生构造、规律类推法。提高地质构造分析的准确性 。

Due to the specific working environment of coal mining, security is of most important. Hidden danger is closely related to water,fire,gas,coal dust and roof. Among these factors, water, gas and roof are directly connected with geological structure. Fault is one of the key geological elements affecting the security of coal mining and thus links with the economical and social benefit of the coal mine. Fault analysis and prediction are associated with the secure operation and the rational development and utilization of the coal resources. Based on the fault distribution of Suli coal mine, in conjunction with empirical experience, several methods on prediction of small medium scale faults have been discussed, such as strata comparison, tectonic comparison, characteristics analysis of fault zone, induced structure on the sides of a fault, regulation analogy, etc. The accuracy of the prediction on geological structure has been improved and therefore, the security of mining is guaranteed.
